Abstract

This is a novel process for the preparation of m-phenoxybenzaldehyde, a useful and valuable intermediate for the synthesis of pyrethroid type pesticides. The process comprises halogenation of m-phenoxytoluene on the side chain, in an inert solvent and in the presence of free radical initiators or strong light to a mixture of the corresponding mono and dihalo derivatives, and conversion of the mixture to m-phenoxybenzaldehyde by a Sommelet-type reaction.
